Influence Of Microalloying Precipitates On Bauschinger Effect During Uoe Forming Of Line Pipe Steels, Andrii Kostryzhev, Martin Strangwood, Claire L. Davis
Faculty of Engineering and Information Sciences - Papers: Part A
Large diameter steel line pipes are generally produced by cold deforming hot rolled or thermomechanically controlled rolled (TMCR) plate by the three-stage 'UOE' process. Pipe strength has been found to increase or decrease relative to the plate, depending on the steel grade and plate processing history. The strength increase is due to work hardening whereas any decrease in strength arises from the Bauschinger effect due to the reverse cold deformation of the UOE process. The steel chemistry, through the presence of strengthening microalloy precipitates, and prior processing, through the size and distribution of microalloy precipitates and the presence of retained …

Orientation Effect On Mechanical Properties Of Commercially Pure Titanium At Room Temperature, M Battaini, E V. Pereloma, Christopher Davies
Faculty of Engineering and Information Sciences - Papers: Part A
The effect of sample orientation on the mechanical properties of commercially pure (CP) titanium plate with a transverse split basal texture was investigated at room temperature (RT) using plane strain compression (PSC). A large variation in flow stress of up to (EBSD) and calculating Schmid factors for all important slip and twinning modes. Importantly, the Schmid factors were calculated for all orientations in Euler space because there are significant variations over all orientations for the PSC stress state, unlike uniaxial compression or tension. The Schmid factor analysis and twin data for the wide variety of orientations tested enabled the conclusion …
